--testing-mode gives this gsl_matrix to reg_sweep:

1.9111902193650001 -504.13075111149146  1552.549464380658
0                   19.278766355808902 -1662.0047084369501
0                   0                   215.25642906983995


Without that option, reg_sweep gets this matrix:

1.9111902193650001  2.4083892281683541 -4.7878197279351395
0                   19.278766355808902 -61.698877095504059
0                   0                   215.25642906983995

The second one is correct for the syntax in regression.sh.

I figure that I broke a gsl_matrix_view in linreg.c while fixing bug 23567, and
that's what I'm looking for now. What I'm wondering is why such
an error would show up with --testing-mode.
